ChartDirector 7.0 (ASP/COM/VB Edition)

Data Table (1)



This example demonstrates putting a data table under the x-axis.

In ChartDirector, the labels in a label based x-axis (that is, axis configured with Axis.setLabels or Axis.setLabels2) can be converted to a table using Axis.makeLabelTable.

Note: Axis.makeLabelTable is only supported on a label based axis with no label stepping. You should not use this method with other axis configuration.


The Axis.makeLabelTable returns a CDMLTable object representing the table. It can be used to add more content to the table and to configure the appearance of the table.

In this example, 3 rows with alternating background colors are added to the table using CDMLTable.appendRow. The cells in the rows are filled with data values using CDMLTable.setText. A column is added to the left of the table using CDMLTable.insertCol, and filled with the legend icons obtained using Layer.getLegendIcon.
